Description

(54) DEVICE FOR CONDENSION OF HYDROSMESI

The invention relates to the hydraulic transport of granular materials and is intended to thicken the slurry, remove clay and silt impurities, and increase the modulus of sand size.

A cyclone is known, comprising a housing, a tangentially located inlet pipe, a tube on the cylindrical part of which are screw blades, a drain pipe for clarified slurry and a drain pipe for semi-bright slurry (1).

 The disadvantages of this cyclone are cumbersome, structural complexity in "there are large hydraulic losses, due to which it is impossible to transport a condensed product without additional equipment.

The closest to the technical essence and the achieved result of the present invention is a device for thickening the slurry, including a housing, a discharge chamber, drain pipes and directing ribs (2 ..

. The disadvantages of this device are the large metal intensity and complexity of the structures; during operation, large hydraulic losses are created, since the small head in the feed pipe does not allow the apparatus to work.

besides, periodic sampling of condensed slurry is impossible.

The purpose of the invention is to increase the effective operation of the thickener in various modes of its operation and at different geometrical orientation of the device body.

This is achieved by the fact that the unloading chamber is made in the form of an expanding cone, in which it is installed with a possibility of movement relative to the longitudinal axis of the device of the drain branch pipe, and the guide ribs are installed inside the housing.

FIG. 1 shows a slurry thickening device, a product section; in fig. 2 is a section A - A in FIG. one.

The device has a cylindrical body I 1c inside which screw helical ribs 2 are installed, a discharge chamber 3, a drain pipe.4 for a thickened slurry, a drain pipe 5 for a clarified slurry.

Viite straightening ribs can

fr can be carried out in different designs from a predetermined mode of operation of the device and in the process of work can be replaced without much effort, since the cylindrical body to which they are attached is 25 a pipe section of the same diameter as h slurry line equipped flange connections. The device works as follows. The initial slurry from the pressure slurry line is closed into a cylindrical body. Under the action of helical ribs, the slurry spins around the axis of the pipeline. The soil particles act by screw threading ribs, pressing them against the walls of the cylindrical body, as well as G1 centrifugal force, which also tends to press them against the walls of the cylindrical body. , The concentration of soil particles over the cross section of the hull becomes uneven. In the middle of the stream, a zone with a small concentration of particles is formed, and along the perimeter - with an increased concentration. The design of the discharge chamber allows the selection of a thickened slurry around the perimeter of the cylindrical body, and the clarified slurry - from the central part of the stream. The operation mode of the device can be adjusted using the drain nozzle by moving it in the direction of the longitudinal axis of the device, and it is also possible to install screw flow ribs of various shapes. If the apparatus operates in the mode when the slurry enters it with a low inlet pressure, then the screw ribs and solid soil can be removed.

Fig} 4 which at the bottom of the pipe will be discharged into the pipe for the condensed product, and the clarified slurry will be fed into the pipe for the clarified hydraulic fluid. Using this device in a 3 m discharge line during sand or sand-gravel mining will allow to transport the slurry high concentration, as well as measure the modulus of sand size and reduce the content of clay and clay njJHMesey in the sand. The invention The device for thickening the slurry, including the body, discharge. chamber, drain nozzles and straightening ribs, characterized in that, in order to increase the efficiency of the thickener, the discharge chamber is designed as an expansion KO} iyca, which is mounted for movement relative to the longitudinal axis of the drain nozzle device, and the diverting ribs are installed inside the case.
